k really need some help here. i just bought my car last week and all of a sudden when i put a radio in it the cars memory quit working like the clock on the dash and my radio keep resetting and then my dome light doesnt come on anymore when i open the door but it comes on when i put my key in the ignition. any help will be greatly appreciated because i really cannot afford to rip my car apart trying to find an exposed ground wire exposed which i dont even think that is whats wrong with it.
